I dont know if C&R is the best place for this, but I figure the mods will move it if they deem necessary

I have an Ishapore 2a in .308 I am looking to mount a scope on. I really prefer not to dril and tap as the rifle is primo condition (well, except for the spray paint somebody did to it, but that is getting changed). So through my research, it appears to basically be the same receiver as a #1 MkIII. From what everyone says on the all knowing internet the B-Square mount seems to be the hot ticket for no gunsmithing mounts. Problem is, I can't seem to figure out which mount to order?

Midway, I got a scope mount that goes in place of the iron sight. I will PM you the link...

I have never found a scope mount for the 2A1 or No.1 Mk3 which doens'r require drilling and tapping and genuinely stays on it's zero. Honestly I wouldn't bother. What I would do, because I assume this is an ailing eye thing rather than thinking the rifle will be an MoA shooter, is go on ebay. Somewher there you can find a guy who makes and aperture which replaces the V slot on the standard rear sight. it makes a fairly significant difference and costs about $20. Also the paint is standard Indian army paint for protection for tropical humid environment so it's the actual original finish.
